Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] like Figure 1-5 As shown in the figure, an embodiment of the present invention discloses a smart public toilet ventilation device, including a wall 1, a frame 5, and a dustproof mesh plate 9. The wall 1 has an installation cavity 2, and one end of the wall 1 has two guide holes 3. Positioning holes 4 are provided on both sides of the inner walls of the two guide holes 3. Guide blocks 12 are installed at the upper and lower ends of the frame 5, and each guide block 12 contains an installation component 13. A ventilation fan 7 is installed inside the frame 5, and one end of the frame 5 has two rectangular holes 6. Both ends of the dustproof mesh plate 9 have locking blocks 10, and each locking block 10 contains a replacement component 11. The inner walls of the two rectangular holes 6... The upper and lower walls of the cavity are provided with insertion holes 8; the frame 5 and the ventilation fan 7 are slid into the guide hole 3 through the guide block 12. With the setting of the installation component 13, the ventilation fan 7 can be installed on the wall 1 to realize ventilation of the public toilet. It is easy to disassemble and assemble, and convenient for subsequent inspection and maintenance. The dustproof mesh 9 can be inserted into the rectangular hole 6 through the clip 10. With the setting of the replacement component 11, the dustproof mesh 9 can be installed and fixed, thereby preventing dust from entering the public toilet. It is also easy to disassemble, replace and clean the dustproof mesh 9, and avoid the mesh from being blocked and affecting the ventilation effect.

[0026] Mounting assembly 13 includes two square holes formed within guide block 12. A fixing rod 131 is installed in each of the two square holes. A square block 132 is slidably connected to each of the two fixing rods 131. A through plate 133 is installed at the far ends of the two square blocks 132, and the through plate 133 is slidably connected to guide block 12. A screw 134 is rotatably connected to each of the two square holes, and the screw 134 is threadedly connected to the square block 132. A rotating rod is installed between the two screws 134, and the rotating rod is rotatably connected within guide block 12. A driven cone is installed on the outer surface of the rotating rod. Gear 135 and guide block 12 are rotatably connected to a rotating rod. One end of the rotating rod is equipped with a driving bevel gear 136, and the other end is equipped with a handwheel 137. During installation, the frame 5 and the ventilation fan 7 slide into the guide hole 3 through the guide block 12. Rotating the handwheel 137 drives the rotating rod to rotate, which in turn drives the driving bevel gear 136 to rotate, which in turn drives the driven bevel gear 135 to rotate, which in turn drives the rotating rod to rotate, which in turn drives the two screws 134 to rotate, which in turn drives the square block 132 to slide on the fixed rod 131, thereby driving the through plate 133 to slide and lock into the positioning hole 4, thus completing the installation.

[0027] like Figure 4 As shown, in some embodiments, the driving bevel gear 136 and the driven bevel gear 135 mesh with each other; this facilitates installation.

[0028] like Figure 4 As shown, in some embodiments, the through plate 133 slides within the positioning hole 4; this facilitates installation.

[0029] like Figure 5 As shown, in some embodiments, the replacement component 11 includes four guide rods 111 installed within the locking block 10. Two guide rods 111 on the same side are slidably connected to a slider 112. Insert blocks 113 are installed at the far ends of the two sliders 112, and the insert blocks 113 are slidably connected to the locking block 10. Springs 114 are installed at the near ends of the two sliders 112, and all four springs 114 are connected to the locking block 10. A take-up roller 115 is rotatably connected within the locking block 10. A rocker arm 116 is installed at one end of the take-up roller 115 for winding. Two connecting ropes 117 are connected to the outer wall of roller 115. The two connecting ropes 117 are respectively connected to two sliders 112. By rotating the rocker arm 116, the take-up roller 115 is driven to rotate, which winds up the two connecting ropes 117 and causes the sliders 112 to slide on the guide rod 111, compressing the spring 114. This causes the insert block 113 to slide into the locking block 10, which then locks the locking block 10 into the rectangular hole 6. As the spring 114 returns to its original position, the insert block 113 is locked into the insertion hole 8, completing the installation of the dustproof mesh plate 9, which facilitates dust prevention in public toilets.

[0030] like Figure 5 As shown, in some embodiments, the insert 113 slides within the socket 8; this facilitates installation.

[0031] like Figure 1 As shown, in some embodiments, the guide block 12 slides within the guide hole 3, and the locking block 10 slides within the rectangular hole 6; this facilitates guided installation.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
